I had same issue, managed to play at best 5 minutes without being disconnected or having a freeze and many login attempts failed at all. Was also wondering if its because of my hardware/connection rather than a server issue.
The desktop i'm running the game with is an intel i5 4590 3.3ghz with ati radeon r9 270 2gb and ram 8gb ddr3, should i be able to play the game smooth? my connection also is a bit weak guess thats doesnt help, but i usually play other online games with no problems
